Mikey Garcia will try to show that good smaller fighters can shock good bigger rivals as he steps up two divisions to challenge Errol Spence for his IBF crown

The clash is a match made in heaven — legitimately it can be considered on the same level as great encounters like Ali-Frazier, Leonard-Hearns, Hagler-Hearns, Barrera-Morales and, more recently, Alvarez-Golovkin.

Both are unbeaten. Garcia has won 39 fights with 30 KOs and Spence 24 with 21 inside the distance, so it really is the best meeting the best.

Whoever wins will maintain they are the finest pound-for-pound fighter in he world today, although Vasyl Lomachenko will have something to say about that.

Fans were badly let down by the dreadful anti-climax that was Mayweather-Pacquiao, which failed miserably to live up to its hype.

But I’m confident Garcia and Spence will.

What make this battle even more intriguing is the huge physical discrepancy between Garcia and Spence, who not surprisingly is a 1-4 favourite.

American Garcia, 31, who holds the WBC lightweight title, is under no illusions about the obstacles he has set himself.

And he acknowledges local boy Spence will massively outweigh him by more than a stone.

His father Eduardo and brother Robert, who train him, tried desperately to talk him out of what most boxing insiders regard as a bridge too far.

Because Garcia will also have to cope with considerable height and reach disadvantages.
